GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 667,506, dated February5, 1901.

Application filed Julie 11, 1900. $erial No. 19,839. (No model.)

To all whom, it may concern:

Beit known that we, GAYLARD WV. DENYES and OWEN SCHUTT, citizens of theUnited States, residing at Cassopolis, in the county of Cass and Stateof Michiga n,h ave inven ted certain new and useful Improvements inGrain- Drills; and we do herebydeclare the following 10 be a full,clear, and exactdescription of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in grain-drills, and moreparticularly to that class known as shoe-drills; and its objects are toprovide improved means of applying spring-pressure to each shoeseparately and independently, to provide for allowing each shoe to actindependently of the spring-pressure, to provide for simultaneouslyraising the shoes out of action, to simplify and cheapen the device, andto provide the same with certain new and useful features hereinaftermore fully described, and particularly pointed out in the claims.

Our invention consists, essentially, in the construction and arrangementof the spring in connection with the rocker-arm, shoe, and tube orhopper, as hereinafter more particularly described, reference being hadto the accompanying drawings, in which Figure l is a side elevation of adevice embodying our invention; Fig. 2, a plan View of the same withparts omitted, and Fig. 3 a rear elevation of the same.

Like letters refer to like parts in all of the figures.

A represents a portion of the main frame of the machine, B one of theshoes, it being understood that the machine contains a series of thesame, and D a tube extending upward from the rear of the shoe, it beingunderstood that the machine is provided with suitable means forsupplying grain or seed to these tubes.

0 represents the drag-bars pivoted to the frame at the forward ends andattached to the shoes at the rear and permitting free vertical movementof the shoes. At the rear of each tube and near the bottom thereof is atransverse boss E, to which are pivotally secured by a suitable bolt thelower ends of the springs, which springs are provided withtransversely-elongated links F, slidably engaging the said bolts. Thesprings extend thence rearward and upward, and to increase theirflexibility are coiled at G, near the middle andin vertical planes, andextend thence upward and forward to points nearly above their lowerends,where they terminate in eyes I, pivotally engaging suitable lateralprojections on the end of a rocker-arm J, attached to a rock-shaft K,extending across the machine and provided with one such arm for eachshoe B. Said rock-shaft is rotative in suitable bearings and adjustedand held by means of a lever L, having a latch M engaging a suitablesector N. Ihe springs are shown arranged in pairs for each shoe; but itis obvious that a single spring would be operative.

From the foregoing description the operation of our device will bereadily understood. By adjusting the lever forward the arm is depressedand the spring will yieldingly press the shoe into the soil. Byadjustingthe lever backward to a middle position the spring isinoperative and the bolt plays freely in the elongated lin k F,the shoeoperating by gravity alone. By adjusting the lever farther backward thespring will yieldingly support the shoe and partially neutralize theaction of gravity and cause it to run shallower, and by turning thelever further still to the extreme back position the shoes will besuspended clear of the soil by means of the springs and thrown whollyout of action. The springs thus act in both directions from the normalor nontension position, which tends to avoid changing the set or form ofthe springs and keeps them longer in good order. Itwill further beobserved that the structure is very simple and consists of but few partsof easy construction, the connection between the arm and tube or shoeconsisting of but two continuous flexible rods of suitable metal.

Having thus fully described our invention, what We claim, and desire tosecure by Letters Patent, is

1. In a grain-drill in combination with a vertically-adjustable support,and a Verti- IOO cally-movable shoe, means for connecting the sameconsisting of a continuous flexible rod, bent to form an eye at one endand bent to form a horizontally-elongated link at the other end,substantially as described.

2. In a grain-drill in combination with a vertically-adjustalile arm,and a verticallymovable shoe, each having lateral projections,continuous flexible rods, hav ng eyes at one end engaging theprojections on the arm, and transversely-elongated links at the otherend engaging the projections on the shoe, said rods also being bent nearthe middle, substantially as described.

3. In a grain-drill, in combination with a vertically-adjustable arm anda verticallymovable shoe, a continuous flexible rod, formed at one endinto an eye, and formed at the other end into a transverselink, andcoiled in substantially a vertical plane, and pivotally connected to thearm at one end, and slidably connected to the shoe at the other end,substantially as described.

4. In a grain-drill, the combination of an adjustable rocker-arm, avertically-movable shoe, a tube projecting upward from the shoe, aflexible rod pivoted to the arm at its upper end andextending rearward,and coiled at the middle portion, and attached at the lower end, to thetube, substantially as described.

5. In a grain-drill, in combination with a vertically-adjustable supportand a vertically-movable shoe, a spring attached to the support at theupper end, extended thence rearward and downward, and coiled near themiddle, and thence extending forward, and provided with avertically-elongated link slidably connected to the shoe, substantiallyas described.

6. In a grain-drill, a shoe having drag-bars pivoted to the frame, atube extending upward from the rear of the shoe and having a transverseboss and a bolt, springs having transversely-elongated links slidablyengaging the bolt and extending rearward, and thence coiled in verticalplanes and thence extended upward, and provided with eyes at the upperend pivotally engaging a rockerarm mounted on a rock-shaft having alever, latch, and sector, substantially as described.

In testimony whereof we afiix our signatures in presence of twoWitnesses.
